DESCRIPTION

The HCC40101B (extended temperature range)

and HCF40101B (intermediate temperature range)

are monolithic integrated circuits, available in 14-

lead dual in-line plastic or ceramic package and

plastic micro package.

The HCC/HCF40101B is a 9-bit (8 data bits plus 1

parity bit) parity generator/checker. It may be used

to detect errors in data transmission or data retrie-

val. Odd and even outputs facilitate odd or even

parity generation and checking. When used as a

parity generator, a parity bit is supplied along with

the data to generate an even or odd parity output.

When used a parity checker, the received data bits

and parity bits are compared for correct parity. The

even or odd outputs are used to indicate an error in

the received data. Word-length capability is expan-

dable by cascading. The HCC/HCF40101B is also

provided with an inhibit control. If the inhibit control

is set at logical ”1”, the even and odd outputs go to

a logical ”0”.
